I can say that i have this bug with n3ds also. But only in the building Grid Windows. Try it with torches! Make 20. Select them to place oneone- PUFF. only 19 are selected.
Okay, my torches do not dissapear when in the build grid window. But when I do the inventory glitch that the others have mentioned (heart crystals/mana crystals and confetti guns dissapearing when you leave the inventory menu), thats when one of my torches goes missing...However, coloured torches and Tiki Torches don't dissapear when I try the glitch on them.
Also, here are some other items I have found that dissapear by one when I highlight them in the inventory and then leave the inventory menu: Beenades, Spiky Balls, Shuriken, Throwing Knife, Vile Powder, Glowstick, Smoke Bomb, Purification Powder
So whatever this glitch is, it seems to affect many different items. The strangest part of the glitch of course is the fact that some people seem to lose items that other players do not (heart/mana crystals). And the fact that someone said they lose torches in the item grid menu while I lose them in the inventory menu...
There are probably more items affected by this glitch, I can't test them all though. Looks like it is a certain type of item this glitch affects (useable items). But not every useable item though, since the coloured torches, bombs and grenades were not affected by the glitch at all.
This seems pretty big I think
@Deanzor . Not game breaking, but can be annoying to some players nonetheless, especially those who lose heart and mana crystals.
Edit: Okay, I know how to reproduce the "torches dissapear in the item grid menu" glitch now. If you have a weapon equipped at the moment, and then you switched from the weapon to the torch (can be done by touch screen or by the L and R buttons), the torch count will go down. However, switching from a tool to a torch, or another item/block to a torch does not reproduce this glitch. It only happens when switching from a weapon.
Edit 2: Okay...this is just weird. The torch count only goes down when using a certain weapon, other weapons will not make the torch count go down. At first I thought "maybe the weapon that is first on your hotbar is the one that triggers the glitch", but this is not the case. Right now, the only weapon that makes my torch count go down in the build grid menu is my Vampire Knifes...
Edit 3: I discarded my Vampire Knifes...now none of the items I mentioned earlier gets lost when I leave the inventory...
Last edit of the night: Okay, that confirms it! When using any other character, those items I mentioned earlier (Beenades, Spiky Balls, Shuriken, Throwing Knife, Vile Powder, Glowstick, Smoke Bomb, Purification Powder, Torches, Confetti Gun) are not affected by the "disappearing when leaving the inventory" glitch anymore. I have tried equipping every weapon that I have available...This glitch only happens when I have the Vampire Knifes in my HOTBAR!
